Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released. A nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy.
Advances in the potential energy source may not be about electricity, at least at first.
Although tritium is volatile and biologically active, the health risk posed by a release is much lower than that of most radioactive contaminants, because of tritium's short half-life (12.32 years) and very low decay energy (~14.95 keV), and because it does not bioaccumulate (it cycles out of the body as water, with a biological half-life of 7 ...
Tritium can be contained in water released from a nuclear plant. The primary concern for tritium release is its presence in drinking water, in addition to biological magnification leading to tritium in crops and animals consumed for food. [28] Legal concentration limits of tritium have differed greatly from place to place (see table right).
"[Fission and fusion] both release energy, but fusion releases much more energy," Kritcher said, "And it's also clean, because of the different fuel types, and it doesn't produce long radioactive ...
Fusion processes are very sensitive to temperature so the star can produce more energy to retain hydrostatic equilibrium, at the cost of burning through successive nuclear fuels ever more rapidly. Fusion produces less energy per unit mass as the fuel nuclei get heavier, and the core of the star contracts and heats up when switching from one ...
Scientists at Lawrence Livermore National Laboratory say they've produced a nuclear fusion reaction that generated more energy than it required to ignite.
Energy produced by coal, petroleum, natural gas and hydropower has caused more deaths per unit of energy generated due to air pollution and energy accidents. This is found when comparing the immediate deaths from other energy sources to both the immediate and the latent, or predicted, indirect cancer deaths from nuclear energy accidents.
